Lamiess Lms 154 Steel-Rimmed Oval Badge Reel, Clear Yellow, Pack of 50

Badge reels are generally used to fasten ID badges or name tags to clothing.

The working mechanism of a badge reel is similar to that of a clothes peg.

Pressing opens the clip of the badge reel; the collar or pocket of the garment is placed into the opened part, and the pressed end is then released.

Held in place this way without damaging the garment, badge reels are also far less likely to fall off or get lost. 

They come in varieties such as steel-rimmed badge reels, lanyard-mounted badge reels and belt-clip badge reels.
